    摘要： A method and system of performing an intravascular procedure at a treatment site in a vessel of a patient. A device creates a seal to prevent the flow of blood during the treatment of vascular disease. A seal may be formed between the distal inside diameter of a sheath or catheter such as a guide catheter as well as within a vessel, such as an artery or vein. An elongated device having a distal portion extending from the catheter and having a fluid impermeable membrane disposed about at least the distal end of the device is used to seal the vessel. The system includes a device to occlude blood flow and a distal protection device to filter or remove embolic debris.

    摘要： Everting filter devices and methods for using the devices, including using the devices as intra-vascular filters to filter thrombus, emboli, and plaque fragments from blood vessels. The filter devices include a filter body nominally tubular in shape and having a large proximal opening. The filter body can extend from a proximal first end region distally over the non-everted exterior surface of the filter, further extending distally to a distal-most region, then converging inwardly and extending proximally toward the filter second end region, forming a distal everted cavity. The degree of eversion of the filter can be controlled by varying the distance between the filter first end region near the proximal opening and the closed second end region. Bringing the filter first and second end regions closer together can bring filter material previously on the non-everted filter exterior to occupy the distal-most region.

    摘要： The present invention provides a medical device retrieval system comprising a working element carried by a flexible, elongate shaft, the working element having a proximal profile and the shaft extending proximally from the working element and a retrieval cover slidable carried along the shaft of the medical device, the cover having a deployed configuration and being capable of being compressed into a compressed configuration for deployment, yet resiliently substantially return to the deployed configuration; the cover in its deployed configuration having a radially reduced proximal portion, a distally open distal end defining a distal opening having a maximum dimension at least as great as the maximum dimension of the proximal profile of the working element of the medical device, and an elongate internal recess defined between the proximal portion and the distal end.
